Integrated CMOS linear image sensors feature 2,000 DPI

The 600μm pixels are pitched at 12.7μm (2,000DPI) without gaps or distortion and are thus suitable for use in triangulation or spectroscopy applications, for example.

The integrated control logic needs only a start and clock signal to generate the light/voltage conversion at the analogue output. The asynchronous, global, electronic shutter allows a flexible control of the exposure time.

To perform a coarse quick scan, for example, the physical resolution of 2,000DPI can be electronically reduced by a factor of 2, 4, or 8. The resolution reduction is achieved either by averaging (gain unchanged) or binning (gain increase).

The iCs require a 5V supply voltage. To ease the interfacing with 3.3V systems, for example, the analogue output driver can be supplied from an additional lower voltage.
